Cooling Fan Operation Function (N35) - Omron SYSDRIVE 3G3JV Series User Manual

Advanced Operation
Set Values
This parameter is used to set the electronic thermal protection constant of motor over-
load detection OL1.
The default setting does not need any changes in normal operation.
To set the parameter according to the characteristics of the motor, confirm the thermal
time constant with the motor manufacturer and set the parameter with some margin. In
other words, set the value a little shorter than the thermal time constant.
To detect motor overloading more quickly, reduce the set value, provided that it does
not cause any application problems.
